Implementation and Evaluation of Distributed Hash Table Using MPI

Abstract

The current Internet traffics depend more on the P2P type???communication than the legacy client-server type ???ommunication. The P2P communication has been applied to diverse systems such as the VoIP and the file sharing system for the P2P potential ability. The distributed file sharing system over the P2P network using DHT (Distributed Hash Table) can especially provide the quick search, while the file accesses from the remote user does not follow the uniform distribution causing the degradation of searching performance. In addition, the DHT algorithm has been mainly evaluated using simulators leading to the difficulties to evaluate the actual performance of message transmission on real world. In this paper, we propose the new framework to implement DHT algorithm into the real environment using the MPI (Message Passing Interface). Especially, the step wised implementation is applied into our proposed system to clarify the performance deadlock on the real world. The proposed P2P system implemented on the MPI middleware is effectively evaluate the performance also is able to be used the file sharing system over the Internet.
